Methods and/or apparatuses for magnetic resonance imaging (MRI) and/or magnetic resonance spectroscopy comprising a superconducting gradient coil module configured for cryogenic cooling. Such a superconducting gradient coil module may comprise a vacuum thermal isolation housing comprising a double wall hermetically sealed jacket that (i) encloses a hermetically sealed interior space having a first vacuum pressure, and (ii) substantially encloses a vacuum space having a second vacuum pressure; at least one superconductor gradient coil disposed in the vacuum space; a thermal sink member disposed in the vacuum space and in thermal contact with the at least one superconductor gradient coil; and a port configured for cryogenically cooling at least the thermal sink member. |
